Objective:The aim of this study was to establish an HPLC method for simultaneous determination of the contents of Rosemary acid and Luteolin in defatted Perilla. Method: Diamonsil C18 (4.6 mm×250 mm
5 μm) column was used
with methanol-0.1% phosphoric acid(55: 45) as mobile phase. The flow rate was set at 1.0 mL · min-1
the detection wavelength was set at 330 and 350 nm
with the column temperature at 30 ℃. Result: The linear response ranges were 9.91-158.55 mg · L-1 with regression curve Y=108.83X+0.136 8 (r=0.999 9) for rosemary acid
and 0.997-15.952 mg ·L-1 with regression curve Y=119.63X-3.677 8(r=0.999 9) for luteolin. The average recovery of rosemary acid and luteolin were 99.68% and 100.34%
respectively (RSD 2.01%
2.86%). Conclusion: A simple
accurate and reproducible HPLC method has been provided for simultaneous determination of rosemary acid and luteolin in defatted Perilla.
